Bootstrapping the maven build

1. Install the tools repo.
2. Install the testmodels repo.
3. Install the parentpom repo.
4. Install the argouml repo. This relies on static parts in the ad.hoc. https://argouml-tigris-org.github.io/tigris/maven2/ store.
5. Install the test-i18n-properties repo.
6. Install he argouml-cpp repo.
7. Any i18n-repo.
8. Any other repo.

The same steps are probably required when changing versions.

Details:

• test-i18n-properties and argouml-cpp are independent and can be done at the same time.
• The other repos are independent of test-i18n-properties, argouml-cpp and the i18n repos. They can be started immediately after argouml.
